I got your filter from your Hong Kong dealer Wilco Group limited and I had it installed on my 1983 Mitsubishi Lancer. It fits and works perfectly,,,, please continue manufacturing filters specially for old cars from the 80's.. K & N more power to you....
you're the best...

I just changed my Proton Persona Auto Filter Element (to a K&N) and man what a difference it made to the acceleration of the car. It now down shifts less. It is so exciting to get up every morning to drive the car. I am sold for life!

My wife and I will not purchase another air filter from anybody but K&N. As soon as as I knew how well your air filters worked it took me a couple of years to convince my wife who at that time only relied on her Father's advice. 5 cars later she will put nothing but a K&N air filter in our cars and neither will her father. My wife has even gone to the point of her excessive frugalness to buy one even 2 days after she purchased her new car and took it in for a check up. They put a new filter in then 2 days later you guys came out with 1 for her car and she bought it. The whole time after purchasing the car, her day by day checking to see if you had made a filter for her 2008 Mitsubishi Lancer GT. I have never in my life seen her wait so expectantly for anything to come out on any kind of market food, chef, Make-up, kitchen appliance, ETC as she did your product. I have never been so flabbergasted by anything in my life. I owe it all to your products. Thank you for many years of quality and enjoyment from my vehicles. Please don't stop.
